Finally a highend speaker kit on youtube! :D

I am somewhat familiar with this kit. I’ve seen it before. I think it’s amazing. I think you did an amazing job and I’m glad you enjoy them and they sound wonderful. I appreciate the fact that you wanted to do everything yourself and now that you’ve done everything yourself. And they’re done take them to somebody who’s a professional and have five coats of high gloss piano black lacquer sprayed on them or walnut veneer or whatever you want and make them look really nice. I realize how they look has nothing to do with how they sound but if they don’t look good it does matter. You will be glad you did.

I loved your build. I've been a diy speaker enthusiast for quite a long time. Years ago, I built a couple of subs utilizing the SEAS L26ROY 10" with plate amps and paired them with a couple of Zaph Audio ZA5.5's, both from Madisound. The setup sounded very good, especially the low end. The SEAS back then were about half the cost they are now. Recently I went with another Zaph design, the ZRT 2.5, and revamped the SEAS sub enclosures to match the new speakers. I am extremely happy with their sound, about the best I've heard, the low end is still fantastic. I certainly would've considered this kit if my budget was a little higher, but I'm extremely happy with the ZRT's. Thanks for sharing.

Thanks for putting this video together in an easy to follow tutorial. I appreciate your personal input at times too. Nice work!

Wow, 20 to 20 in a monitor 😮. I need this in my life.

I just had to delete my comment as I went back and read the description again. They went full active crossover with DSP for these speakers and that's really quite a bold move. I'm a huge fan of speakers that don't need separate subwoofers and these really do look like a great option if you're considering something like the KEF R3 Meta but wanted active speakers with monitoring potential. I think the only change I would make, if you ever want to refinish the cabinets in the future, would be to add corner bracing to the front baffle and then use your table saw set at 15, 30, 45, and 60 degrees to pre-form the edges of the front baffle so you can sand them down into a massive round-over to reduce baffle edge diffraction. It's not strictly necessary, though. In case you were curious: you can totally just use truck bedliner to paint your speaker cabinets. It has the benefit of being incredibly durable, but also offers sound damping effects as well due to the thickness and density of the material, but also due to the high-durometer silastic nature of the material.

I had the good luck of buying 2 of the first iterations of this Seas coax back in 2012. To this day the speakers I developed around this coax are in my main listening system to this day and I'm looking at them right now. I think I will try teaming with a ScanSpeak 30W subwoofer and gauge the results. this is an amazing build and thank you for sharing your insights.

Really well done video and edit. Excellent choice on speaker kit. As a contractor I winced at your use of the table saw.. never run it with the balde that high.. it cuts the same when it is just getting thru the top of the wood and teter tottering kneeling over that high of a blade make me hold my breath and pray for you.. great work but sketchy and janky table saw location and use. Now that being said I appreciate the content. Truly love audio and video. Prayers

Hi , I have a pair of Transmission Line cabinets that I built myself about 40ys ago, they had Peerless and they sounded great, until one of the drivers popped, so I contacted Eric at Soundimports from the Netherlands, and they set me up with 8 inch drivers and tweeters from, SEAS , 150w NAD AMP , And what a transformation these now sound amazing, I am in my 70s and I listen to classical heavy metal the blues and Viking music just name a few bits, Luckily, I live by myself in the French countryside, and I enjoy my music to say the least, Very interesting territorial on building your SEAS audio monitor speakers, 🔊, Phil from the moulin France .

Such a giant effort to film and document all of this, amazing work! Thanks for putting it together! Seeing you squatting down at the garage floor for hours cutting and routing the panels, I almost want to buy you a pair of saw horses, so that you can work on a table standing up, man! 😅

Great work. I can appreciate the effort and amount of time dedicated to producing a masterpiece like this.

I liked how you were able to fold all of the side panels together with the blue tape

Great details and excellent build. Respect from India.

Amazing work and video ! I was searching for such a long time an explanatory video to help me build my own 3-way Studio Monitors and yours is by far the best !!! Thx a million !

Amazing video, very well pit together man! Thanks you for the time, it defensively will help a lot of people. It would be amazing to be able to upload Sound ID profiles.

Great vid. Thanks for the time and energy it took to make it. 👍

Not to knock this guys efforts, time, blood, sweat, tears and occasionally annoying the neighbors. I guess I would say "These are the best speakers I ever heard". 😂😂😂😂

Excellent work on this 👏👏👏

very cool and complete video on assembling this kit! Looks suitably high end.. but wow configuring the filter studio software looks way complicated

I must congratulate you on superb desicion and making super build video. Top class and first one of this category

Great job! Ive been curious about the coax driver since the 1st version 10 yrs ago. It's fun to watch the build with intelligent narrative.

Nice :) The correction curve for the sub is crazy, but the only way to reach sub level in a closed box with this monster of a woofer. Really impressing this possibility. You left some room for built upgrades, big rounded corners to improve interference in the mids and some other details, but a solid job you've done. I like the idea of the coax for the studio monitoring, good to work with. For home use I would go for seperate drivers to avoid IM and waveguide effects between them.

If you put the drivers upside down you can move easily position them to drill the pilot holes for mounting and or putting in fittings to use bolts. These look pretty awesome!

You could fit a simple on-off toggle breaker switch on the fan amp module so as to be able to turn the fan of during critical times...the fan should only kick in if running above a preset temperature setting...eg...running the amps/speakers at loud level's for extended periods...that's a good quality looking bass/sub unit...i used to use SEAS drive units back in the '80's to design various loudspeakers...my favourites built were 3-way transmission line speakers with 8" bass units, 5 1/4" mid units & 1" silk dome ferro-fluid cooled tweeters with a very low 550hz resonance, the bass rolled in at 200hz which was the speakers -6db baffle step point, as the bass unit was 90db 1w/1m it matched the second order x-over on the midrange unit nicely,200hz - 2.2khz, padded the tweeter down with a 3rd order x-over with an L resistor set up to match the tweeter levels with the midranges...i bought the best polypropylene caps, air cored inductors, high quality resistors, 4mm connectors etc i could afford at the time..had them for 10yrs, i wish i still had them...the bass & mids were so good, good with so much depth & detail over the whole speakers range -3db 28hz - 25khz....nice speakers,i luv coaxial drive units, Kef Uni-Q, Tannoy, Flyde etc..... Well made speakers bud....

An easier way to braid the wires is to use the drill driver. Clamp one side of wires in the drill driver and the other side in your hand. Now gently let the drill driver turn til the wires are "rigid".

Hi, thank you for making the video. Just liked and subscribed!😎

Super well done video production, you could pass as a Professional 😁😉 The first time I tried a SEAS product was an H253 (IIRC) 1" flush soft dome tweeter, coupled with a SEAS 6.5" paper cone mid/woofer and blew away Polk monitor 4s in 1983 (you were a bit young then 😜) and a guy in the stereo shop (where I'd brought them for comparitive listening) folloeed me to the ARCO and offered me 7 time$ what they co$t me to build. My first successful speaker design/build/sale. I'm going to give this kit serious consideration. 👊😏👍

Amazing build video, thanks for uploading! My only points of note are that the edges could do with being rounded off to reduce diffraction and the leads to the drivers seem a bit low gauge to me.

Yep, I’m gonna have to build these though I have 4 way eve sc408s, I’m going to put these in my mastering room 😉

Great video.. well done👍👍

Thank you so much for sharing.

Congratulations on your new speakers :) Sad that these components aren't available here in Brazil

What a great video. Many thanks for it all. They're clearly wonderful units. The Hypex electronics is obviously great too (I already use an NAD C298 class D amp), and the DSP is the icing on the cake. I live in New Zealand so the freight for the kit would probably be crippling.

Cool tape trick for cabinet panels

I need a speaker to match my Personality. Since these speakers are about perfect, that a BIG NO for me! I think I enjoyed the video more since you added your own personal touches. (Vibe if you will) It made it fun to watch. And Might I say, AMAZING JOB!

@The Social Club Studio Those studio monitors are beautiful, I can imagine how they sound, if I could afford the system and speakers I would love to build it, but I am not a carpenter. Plus I don’t have 5000.00$+ or 6500.00$+ for that type of studio monitors. Great job, I have cheap studio monitors by sterling, a pair of Yamaha HS5 too, KRK Rockit 12 subwoofer

Seas are good speakers and I use them myself in DIY, this project of yours is great for a good price, you make a similar clone of TAD speakers with an added amplifier. Like all loudspeakers, this one also has a downside, I would never use a coaxial mid/tre unit because when moving the midrange, which acts as a waveguide for the tweeter, it strongly colors or changes the treble sound image.

Awesome video!

fantastic and inspirational video !

The sound is decelerated when it meets another medium, and the role of the speaker case is to reduce the sound from the back of the double-sided vibration (front and back) of the woofer. Therefore, the reason for not attaching aluminum plates to all sides is to reduce the sound from other media when it is reflected. to be exposed to. It is exposed to an aluminum plate surface and a surface made of a material different from the aluminum plate.

Damn, y'all given me an anxiety attack when tightening down those drivers. Those are sweet!

only 2min in and im giving you a like!

Tack!

I love the sound its so cool

This was excellent! If I had the time and energy, I'd build a pair of these for sure. What was the final cost of the build in terms of $$$ ??

thank u, this video is super help full and this chanel also , got a new sucriber

Great video only thing I would change are the speaker stands, metal is a poor material to use because of ringing, oak much better and 4 feet are not as good as 3 due to micro vibrations, much easier to get 3 feet to sit probably. Especially with pointed cones, this will prevent smearing in the HF.

I may have missed you pointing it out and you obviously included it in the design but, you could spell out that the Hypex plate amps (and other brands too) are not sealed with regard to air leakage; especially the FA503! Even with a vented enclosure, and certainly a sealed one, you have to fabricate some kind of enclosure or partition for the plate amp to maintain the air seal of the woofer enclosure. It’d be nice if the plate amp was sealed but, you have to accommodate that omission.

Your neighbors must love you...😂

Thanks so much for the video. So wish I could listen to these. Say where did you find the information about the tower versions? I'm not finding anything.

Very nice video. Maybe to long, i used fast forward sometimes. Frequency respons is almost perfect! Maybe i missed when you told what program you used. But i think Rew. (And umik) I use it to. I my small music room response looking not half as good as yours. For 32hz its only a small problem. 8db is nothing for room nod. I got 15db. Going to buy membraneabsorber.

Outstanding!

Whats your opinion on Kali's IN-8 3-Way Studio Monitors if you have one? I've had a small studio and got into recording/mastering years back since ive been playing in bands my whole life and caught the Bug. its still a "Hobby" I guess because its not my main profession but Ive recorded and mastered many works. I used Yamahas HS80s for 7 years and Bought the Kali's specifically their Coaxial Drivers because nobody in the industry had monitors that were coaxial based, unless you had thousands to spend. So for Nearfield I now use the KALI's IN-8 V2's which are great. Also have a pair of DIY 88-Special's for other Reference in my Control Room. I love Audio. Especially Transforming a Customers EP or Mix (whether a master or record and master) and seeing how happy they are. Its always the best part for me.

Loved it! ❤

The aluminum plate is only attached to three sides inside the speaker case, not to all sides. If you stick it on all sides, the sound will be muffled. Attach it to the top and both sides. The bottom and back are not attached.

That's really nice ! Thank' a lot, i was hopping for this video to come till a long time ! Do you use classic MDF for your build or some more heavyest one like HDF ?

Nice work! You’re not going to want to eq frequencies above 100Hz to compensate for in room response. Only correct for direct sound that also is cincistent on and slightly off exis.

Fantastic video! Really enjoyed that. And loved the build because I myself am no cabinet building expert so I laughed at some of the techniques as it’s probably how I would do them and then cringe when watching back. Regarding the poly fill, have you removed the drivers since finishing them? I think there is a chance the material will, over time, fall and clump at the bottom of the cabinet. This will probably have the biggest effect on the coax where you the filling is there to absorb reflected sound reaching the back of the mid driver. Reflex foam is a good alternative as it won’t move once fitted securely. Or some netting could be used to support the poly fill in several layers across the cabinet. Another question, does the optional remote allow you to adjust output volume level of both speakers at the same time? I’m thinking about those that connect a digital source directly that does not have variable digital output. Once again, great video. 👍🏻

Great video! Thx. I would have screwed the Isoacoustics Gaia IIIs to the bottom or the Oreas.

Nice build, long video, but nice build.

I remember the first time I made an enclosure

Feeding the FA Plate amp analog signal, you basically doing double conversion. First digital to analog in your own DAC, then inside the plate amp from analog to digital, AND back to analog.. If you feed it only digital (max sampling 24bit 96kHz), you are skipping the first conversion in your DAC and then the AD-DA conversion inside the plate amp.

very cool and wow i hope to do it one day but smaller. are these are designed for near field mixing or far field non-mixing ?

Great video. You got any buzzing coming from just the tweeter? I build these around the same time as you and I get audible buzzing from my set. I tried a power conditioner with no luck.

Just watching this video and hv a question. Why cut the panels with a 45 instead of straight cuts when it can be finished with veneer anyway? Seems way easier. Maybe I am missing something?

Don't need the closed captioning. you speak clear enough

Superb video of a speaker I want to make so desperately. I want a bookshelf fullrange and this is it. Unfortunately I don’t get seas in my country. Wondering if anyone has some suggestions some other coaxial or FullFrange drivers and subwoofer so like a FAST speaker fullrange assisted subwoofer

anyone know of a place or forum i could possibly get help on building a crossover for to build a non powered pair of these!? i just bought a yamaha AS-2200 and looking for a pair of nice bookshelf speakers.

Awesome

Nice work. Your edits were great and it's obvious you're not married. Wood working....in a kitchen? I don't think so?

wow studio monitors build but video is 1pm to 5pm i am form india time is 12:30 am to 4:30 am is mid night here i am going to slep bey sir

sorry, you moved the router wrong. if the router bit rotates clockwise, please move the router clockwise. with MDF you might not notice that much difference, but with solid wood the edges are cleaner and less "burned" positions. the router bit might jump uncontrolled if moved like you did. This is no criticism, more a safety thing for those who watch the video and starting to build... 👍

Does DAC on these boards supports DSD playback?

Sh’t I just found your channel…!

nice!

Hi I have 2 of the FA 503, ive had it for some time but only recently unboxed them. so all the latest softwire is downloaded but NO pre set filters ? Hypex just keep sending links back to there website which is a complete waste of time. Programing custom filters is extremely long winded , so my questing is , the pre sets you have can you edit ? also where are they and how many is there? all the very best from Japan ..

Really? You've paired Opera music For us to hear while watching you saw? And in what world does that go together? And what makes you think someone watching your program wants to hear that?

is that paint water based? usually you prime or seal mdf w very specific products. i’m a painter but unfamiliar w that product.

Right now I use Yamaha HS8 & HS8s subwoofer and Sonarworks helped me a lot calibrating the speakers to my room . I saw that the sound of SEAS King RO4Y MKIII is flat but do you think that It is necessary to use these speakers with Sonarworks , does it help ?

Can they be placed horizontaly?

Dont kill me for aaking but how are these for audiophile 2.1 setup for music listening and not for mastering?

Damn them floor standing tower build on these things will probably be like what 15-20k a pair? I guess thats amazing for probably the only speakers you will ever need for life no need too ever upgrade or replace these..

what is your recommendation for build an amp for a passive hi fi speaker? ICEpower AS1200 or Hpex ncx500?

Hi, I've had a chance to experience a lot of great monitors Hifi and studio (Amphion 3 way 25a vs Dutch and Dutch 8c in same room, pmc 6-2 with 8-2 subs etc.). You've also experienced ex Machinas and probably other great ones. How close do this compare to them. Ex machinas went even more cutting edge as you said but how would you compare it based on what you've heard? How close this gets. I know that for money nothing can beat them but anyway just to make some feeling about how got they are sounding versu each other? Ex machina pulsar doesn't go to 20hz so here is the one difference on paper. How this translates to reality?

A curved baffle is better for minimising baffle refraction, e.g B&W DM series monitors.

great video, but but but why dsp? yes, ok, you can tune them for ruler flat response, but the sound/input you feed them with can still be bad/incorect. what am i missing?

MDF or wood for the Speaker boxes?

🤘❤️🤘

Was that a real-life deer hanging up there? 🦌

I don’t get the point why you added the 6db on all of the presets since it should be applied within the preset 3 saved.

but i like the sub i must say

Is there someone having the files for CNC cutting machine ?

a rectangular box with a flat baffle , will suffer diffraction effects 🤔

You know, you can use a drill to twist those wires in 2 seconds

Do u know frequency response please?

33:08 Tar patches are effective when the thickness to be treated is equal to or less than the tar patches. So here it doesn't work.

This is great! A new philosophy workshop and Kitchen in one 👍🏻 a Kitshop ! Work and eat cook build drink 🍺 great ! Hmm maybe a toilet 🚽 in the corner ? Everything one needs ! Kitshitshop studio

forgot the midrange diffuser

Anyone doing these passive?

Would have used GR research no rez
